It is apparently a UK company. While there is a lot of international shipping, I think I would be better off sourcing equipment locally unless one could get an excellent deal on it (or there was something very custom). Not all companies do their own machining. For example SWAG Offroad sells Harbor Freight Compatible tubing roller dies, but they outsource all the production locally. Say, one sells a half dozen items a day, it hardly pays to have multi-thousand dollar equipment sitting around.

I do have a mill and lathe, but haven't gone CNC yet. The product design looks fairly straightforward, and could probably be done by hand depending on the volume, but with sufficient volume automation would be nice. The design would be easy once one figures out the ratios, which were posted earlier in this thread.

I went ahead and sent a note to JTek, we'll see if I get a reply back.
